HEATING-DRUM.

Specification of Letters Patent.

Patented Aut 2, 1910.

Application filed January 17, 1910. Serial No. 538,437.

To all whom it may concern:

Be it known that I, PRICE ARNOLD, a citizen of the United States,residing at Fort Worth, in the county of Tarrant and State of Texas,have invented certain new and useful Improvements in Heating-Drums, ofwhich the following is a specification.

My invention relates to drums which are mounted above the heaters andwhich are provided with an inner drum which may be used as an oven forbaking purposes; and the object is to provide means for cleaning theannular space between the inner drum and the outer drum. The space aboutthe inner drum in such devices, particularly about the upper part of theinner drum near the pipe connection of the outer drum, becomes cloggedwith soot and ashes and the only way ever provided for cleaning out thesoot and ashes is by taking the drums down and pounding and invertingthem until they are cleaned out. I have provided a very simple deviceand way for cleaning out the soot and ashes without taking down thedrums, and which can be done at any time with very little effort.

Other objects and advantages will be fully explained in the followingdescription and the invention will be more particularly pointed out inthe claims.

Reference is had to the accompanying drawings which form a part of thisapplication and specification.

Figure 1 is a side elevation of a heating drum. Fig. 2 is an endelevation of the same, showing the improved door closed. Fig. 3 is anend elevation of the same with the improved door opened and showing theimprovement of the head of the old drum. Fig. 4 is a vertical section ofthe drums, taken on the line m-02 of Fig. 1.

Similar characters of reference are used to indicate the same partsthroughout the several views.

In the drawings, A indicates the exterior drum and G indicates theinterior drum. The drum A is provided with a pipe connection E to beconnected with a heater or stove. The drum G is attached to the head Fand is spaced apart from the drum A. A platform or shelf H is usuallyplaced in the drum G for cooking purposes. The drums are provided withthe usual door K. As thus constructed the old drums would become cloggedwith soot and ashes D which would accumulate as indicated by D. The

only way provided in the old drums for taking out the soot and ashes wasto take the drums down. I have provided an improved head F which hasopenings G into the annular space between the drums and I have provideda door B for closing over the head F which door will close the openingsC. The openings C are concentric with the annular space between thedrums and large enough for cleaning the space between the drums. Thelittle rakes in common use can be inserted through the openings C andall the soot and ashes D can be raked down from the upper parts of thedrums and out through the pipe connection E and this can be done withoutdisturbing the drums and without taking the drums down. The door B isprovided with a hinge M and a latch P. The perforations C are located inplanes which are substantially midway between the two pipe connectionsso that the small rakes can reach both pipe connections. After the Vsoot and ashes have been raked down through the pipe connection E, theymay be taken out of the stove with the other ashes.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

1. In a heating device composed of an outer drum and an inner drumspaced apart and having pipe connections for the outer drum; a head forsaid drums attached to said drums and closing one end of the inner drumand having perforations therein opening into the annular space betweenthe drums and a door co-extensive with said head hinged to the outerdrum for closing both perforations at once.

2. In a heating device composed of an outer drum and an inner drumspaced apart and a door closing both of said drums and pipe connectionsfor the outer drum; a head attached to said drums and closing said innerdrum at one end and partly closing said outer drum and havingperforations into the annular space bet-ween said drums and concentricwith said space and located in planes substantially midway between saidpipe connections and a door hinged to said outer drum and closing bot-hperforations at once.

3. In a heating device composed of an outer drum and an inner drumspaced apart to form an annular heating medium and pipe connect-ions forthe outer drum and a door closing both of said drums at one end;

a head permanently attached to the other head hingedly attached to saiddrum outside end of said drums and closing said inner of the lastmentioned head and closing both drum and partly closing said outer drumperforations. and having openings therethrough into the In testimonywhereof, I set my hand in 5 annular space between said drums and 0011-the presence of two witnesses, this 13th day 15 centric with said spaceand located in planes of J anuary 1910.
